In the first draft script of "Shadows of P'Jem" (written while the episode had the working title "Untitled Andorians Return"), Kalev was once referred to (in dialogue) as holding the title of "Supreme Chancellor", termed a "Chancellor" on all other occasions.

Gill's model, Adolf Hitler's Nazi state, was affected by a 1934 referendum as to whether Chancellor Hitler himself might take over the role of the recently deceased President, concurrently with his own governmental duties. Ninety percent of the voting public approved of the move.
